Ark Invest Reshuffles Portfolio, Buys Block and Circle Shares

Cathie Wood's Ark Invest executed a significant portfolio reshuffle on Monday, August 31, 2026, divesting positions in Palantir Technologies and Advanced Micro Devices while substantially increasing its holdings in Block Inc. and Circle Internet Group. The investment firm purchased 456,059 shares of Block, the fintech company led by Jack Dorsey, for approximately $37.4 million across its ARKF, ARKK, and ARKW exchange-traded funds. This acquisition came as Block's stock closed at $82.02, down $1.85 for the session.

The move follows Block's strong second-quarter financial results reported in early August, where the company posted earnings of $1.02 per share and revenue of $6.62 billion, surpassing Wall Street expectations. Block subsequently raised its full-year gross profit forecast to $12.51 billion, indicating 21% year-over-year growth. However, analysts at Mizuho have expressed concerns about rising operational costs, despite the company's 40% workforce reduction implemented in February as part of a shift toward artificial intelligence. Block continues to maintain a substantial Bitcoin treasury of 9,177 BTC, valued at approximately $714 million.
